That Chloroquine and Hydroxychloroquine are being looked at as one potential tool in the current COVID-19 pandemic will likely spur further interest and study in their potential in other health related areas as well.

Among the biological effects of chloroquine and hydroxychloroquine, it is important to highlight their antitumoral properties, likely due to their strong antiproliferative, antimutagenic, and inhibiting autophagy capacities. These effects make these drugs a possible option in the treatment of several tumors in association with radiotherapy and chemotherapy.
